Hibiscus plant named ‘JBN 12002’

ABSTRACT

A new cultivar of  Hibiscus  named ‘JBN 12002’, that is characterized by its well branched plant habit, its large flowers that are deep red in color, its floriferous blooming habit, its glossy green foliage, its vigorous growth habit, and its foliage that is resistant to dieback disease and leaf spot.

Botanical classification: Hibiscus rosa-sinensis.

Cultivar designation: ‘JBN 12002’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus rosa-sinensis named ‘JBN 12002’ and will be referred to hereafter by its cultivar name, ‘JBN 12002’. ‘JBN 12002’ is a new cultivar of tropical hibiscus grown for use as a landscape and container plant.

The new cultivar was developed through an ongoing breeding program conducted by the Inventor in Grand Saline, Tex. The objectives of the breeding program are to develop new cultivars of Hibiscus that exhibit increased disease resistance, glossy foliage, large uniquely colored flowers, a floriferous blooming habit and a well-branched plant habit.

‘JBN 12002’ arose from a cross made by the Inventor in March of 2011 between the Hibiscus rosa-sinensis ‘Kiss and Tell’ (not patented) as the female parent and Hibiscus rosa-sinensis ‘Little Red’ (not patented) as the male parent. ‘JBN 12002’ was selected as a single unique plant from the resulting seedlings in January of 2012.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in Grande Saline, Tex. in February of 2012 by the Inventor. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics the new cultivar. These attributes in combination distinguish ‘JBN 12002’ as a new and distinct cultivar of Hibiscus.

-   -   1. ‘JBN 12002’ exhibits a well branched plant habit.     -   2. ‘JBN 12002’ exhibits large flowers that are deep red in         color.     -   3. ‘JBN 12002’ exhibits a floriferous bloom habit.     -   4. ‘JBN 12002’ exhibits glossy green foliage.     -   5. ‘JBN 12002’ exhibits a vigorous growth habit.     -   6. ‘JBN 12002’ exhibits foliage that is resistant to dieback         disease and leaf spot.

The female parent of ‘JBN 12002’, ‘Kiss and Tell’, differs from ‘JBN 12002’ in having multicolored flowers that are larger in size. The male parent of ‘JBN 12002’, ‘Little Red’, differs from ‘JBN 12002’ in having flowers and leaves that are much smaller in size. ‘JBN 12002’ can be most closely compared to the Hibiscus cultivar and ‘Roller Coaster’ (not patented). ‘Roller Coaster’ is similar to ‘JBN 12002’ in having a floriferous blooming habit and in being well branched. ‘Roller Coaster’ differs from ‘JBN 12002’ in having flowers that are multicolored and in having leaves with a textured surface.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hibiscus. The photographs were taken of seven month-old plants of ‘JBN 12002’ as grown in a one-gallon container in a greenhouse in Grand Saline, Tex.

The photograph in FIG. 1 provides a side-view of three plants of ‘JBN 12002’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘JBN 12002’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Hibiscus.
